Somewhere within Arthur Upfield's travelling dray were the clues to uncovering three acts of murder involving the grifter, Snowy Rowles. Once Upfield had published his crime thriller, The Sands of Windee, West Australian police gave chase, starting with the esteemed author of the Bony detective novels. Here is the evidence.The Murchison Murders were a series of three murders, committed by an itinerant stockman known as "Snowy" Rowles (born John Thomas Smith) near the rabbit-proof fence in Western Australia during the early 1930s. Rowles used the murder method that had been suggested by author Arthur Upfield in his then unpublished book The Sands of Windee, in which he described a foolproof way to dispose of a body and thus commit the perfect murder. - Wikipedia
